Question RAM problem on Rog Strix b450 f Gaming

Nov 12, 2020
Hey guys. So I recently built a pc.

Mobo: ROG strix b450 f gaming
Cpu: Ryzen 5 2600
Gpu: Gigabyte geforce gtx 1050 2gb
Ram: Corsair Vengeance 8gb(8GBx1)
psu: Evga 500BR 500w

So when i first put it together last week i was using my 2 4gb ddr4 hyperx fury ram cards i had from my previous build. After putting it together i got the Dram light and the speaker gave one long beep followed by two short beeps to signal a memory problem. I then sent my ram cards to my friend so he could test them. He tested them and told me they were both dead. So i bought a new stick of 8gb ram from corsair and after adding it to the build to my dismay the same thing ocurred. Ive sent it to my friend for him to test it but im sure he'll say its dead also. I doubt that i'd run into two ocurrences of dead ram. So could the problem be elsewhere? Would love to hear your feedback.
